As every building starts with foundations, our experiments needed a test stand. The design might be difficult, but we had the upper hand. We had some experience with construction so we could plan our work. We knew our manufacturers and they shared more than one good idea with us. Moreover, we could take inspiration from our older projects. And we had top-quality CAD tools to ease our work. And, as you will see, to make the design nice and shiny.
We started our work in free CAD software. This resulted in our first design, shown above. Unfortunately, that was not a perfect solution and with the first iteration of changes, we also modified CAD software.
We wanted to make sure that operating the stand will be easy. We added a simple worker visualization (as in the figure above) to design comfortable heights and distances. The stand also evolved with major changes shown in the pictures below.
The measuring system, placed in the middle, rests on the table as above. Design I had flat bars 3 to control the flatness of plate 1. We abandoned them because design II is machined as a whole piece instead.
More drastic changes can be seen on the engine support table. Initially, in designs I and II, we used trapezoid screws. To increase stiffness we added the second table in design II but resigned from it in design III increasing sizes of below-the-table support instead. It resulted in the final design of the laboratory stand shown, proudly, below.
